What does it do?
Non-contact measurement of distance
with
40um accuracy over full range.
Resolution 10um. Range: 8cm from
face, minimum distance 2.5cm.
Beam width 8mm, 1 degree
divergence.
Fast 1s response (10ms,
100ms or 10s on special
order).
Replaces mechanical vernier-caliper
gages. Replaces mechanical,
inductive,
shafted LVDT, optical and
capacitive proximity distance sensors.
How does it work?
Measures the time-of-flight using
1.4MHz
ultrasonic bursts. It has automatic
calibration and temperature/humidity/gas
composition compensation.
How is it interfaced?
Powered by 17-29V DC, 50mA.
Analog 0-5V voltage output for distance.
Analog combined temperature (speed of
sound)
and envelope profile output, 0-5V.
Who may need it?
- Machine shops:
controlling
dimensions and dimensional tollerance of samples
during machining process.
- Production departments:
checking
alignment and position of
objects in production lines.
Thickness
gageing of sheets and bands.
Measuring bore-hole depth.
Quality testing.
- OEM integrators: integrating it in
the
final product. Measuring of the quantities of
items such as disks or sheets on a
stack.
Paper sheet heights and thickness.
- High accuracy fast air temperature
measurement
(0.02C) under a condition of constant air
composition and humidity.
- Monitoring of gas composition
(providing
that temperature is known).
What is the advantage of Ultraducer over other proximity sensors?
- Much higher accuracy than the existing ultrasonic sensors on the market.
- non-contact (as opposed to LVDT
sensors
that require mechanical
contact with the target)
- more accurate than optical sensors
- longer range and much more linear response with a distance, than capacitive or inductive sensors.
- less restriction on the type of the
target
surface. For example Ultraducer will work against
a transparent target while optical sensors
require non-transparent and reflective targets.
Ultraducer will work with non-conductive
targets while inductive sensors wold not.
- works through small holes down to the
beam diameter; may be used for gageing drill hole depths.

Test
reports:
1) Linearity test (R&D lab)
2) Customer's on-site test:
measuring
profile of a millimeter range microwave dish antena.
Note: beam spread
angle of that particular transducer was enlarged to 3 degrees by
partially
covering
the aperture with a tape, in order to facilitate obtaining good echo
from
a curved surface.
